Hello, hope someone can help with this....Upgraded my OS to Win 7 from XP but into a SATA drive while the XP was in EIDE. That was successlul after I jumpered the SATA300 to SATA150 but when I go to the Bios to make it (SATA) my first boot drive, there is no choice for it in the drop down menu....I can only see the EIDE drives there, and so can't choose Sata to boot first. I have the Asus Socket939 A8V mobo with the latest bios (0229). I want to have My SATA as the boot drive and keep the EIDE as a storage drive. I've tried several things including unplugging the EIDE drive but then the system just tells me there is no master boot drive to boot from. Please help me out here....Thank you.
